Gastric or gastroesophageal junction adenocarcinoma is commonly treated with chemotherapy before and after surgery. The chemotherapy regimen used in our institution, called DCF (docetaxel,cisplatic, 5-fluorouracil) is active, resulting in tumor reduction and dysphagia relief. however, it is toxic, causing approximately half of patients severe inflammation of the mucosa (lining) of the mouth and gut. This results, in turn, in mouth sores, vomiting and diarrhea. Similar regimen called FLOT (5-FU, oxaliplatin,docetaxel) appears to be at least equally active, but less toxic.
